American Ted Purdy won the 2013 Abierto Mexicano de Golf Sunday, rolling in a slippery 8-foot par putt on the final hole for a one stroke victory over Columbian David Vanegas.

Purdy shot a final-round 70, featuring two birdies and an eagle, and fended off the hard-charging Vanegas and talented young Argentine Jorge Fernandez-Valdes.

Purdy credited patience, calmness and two bits of luck for winning Mexico's national championship.

At the par-four No. 8, Purdy's errant shot to the green hit a woman dressed in orange, which is not usually a lucky color to wear on St. Patrick's Day. The ball ricocheted off of her shoulder and came to rest on the green.

"Obviously, it scared me and I apologized to her," Purdy said, "but when I saw [the result of] that shot, I definitely knew that I was going to win the tournament. If it had not stuck the lady, it could have cost me one or two shots," he admitted.

On the final hole, holding a one-shot advantage after a birdie on the par 5 17th, Purdy pulled his tee shot into a stand of tall trees. He was able to punch a full shot through a tiny opening in the canopy of branches and was able to get up and down for par and the victory.

It was Purdy's first victory since the 2005 EDS Byron Nelson Championship on the PGA Tour. He has also notched victories at the Hero Honda Masters in New Delhi, India, and the First Tee Arkansas Classic on the Web.com Tour.
